My husband and I have had many experiences with Froedtert and were always pleased with the care
Marissa was very kind and listened to my concerns. I feel very well taken care by Froedtert.
Maressa is a fantastic health care provider. She is kind, empathetic, and great at listening and talking through my concerns. She always provides insightful solutions when able. I appreciate her so much!
I am a cancer survior and my health and well-being has always been priority number one. I have my own "cancer team!" And I would have made it without them!!! I love each and every person with all my heart! Their jobs ARE NOT EASY but they show up EVERYDAY for their patients!!!!!
Interest, care and concern - all evident
I appreciate Maressa carefully listening to my concerns and answering me without any rushing
I am very happy with the care I am getting. Maressa Sweeney is personable and professional. She answered all my questions and outlined a plan going forward.
Marissa is always been so supportive of me and my cancer care. I truly adore her, and I'm so glad she is part of my cancer team.
Maressa and the staff truly listen to me and always have suggestions for further tests or XR of my hip due to hip pain. She quickly had me get an XR and on my way home she called with the results. She did not want me to wait and worry. I love my entire oncology team of caregivers. I have referred to two friends for breast care to them and both are grateful for the referral.
I love my team. I feel cared for and respected. I wouldn't change a thing.
She is well informed on my status and is very personable. Just a great PA.
I am very grateful to have Maressa Sweeney as my provider. She is personable, smart, dedicated to the welfare of her patients. Her offer to follow up with a phone call when the results of the BCI test results are received is greatly appreciated. Thank you, Maressa!
Marissa is a delight to deal with. She is not only extremely professional but is thorough in her questioning and concerns for my safety and good health.
She showed compassion and concern about what I'm going through and recommended a very good option for my care
She listened and was very concerned about ME. Very thankful for her concern and compassion for me grieving the loss of my grandson. She offered grief counseling. I have been to medical appointments and no body offered it.
Marissa showed care, compassion, undetstanding, and concern for me as a patient and as a person. She made me feel very relaxed and calm as she explained the situation. Most importantly, she expedited the follow-up. She really established and maintains my trust and confidence in my healthcare.
Maressa is friendly, professional and very easy to talk with. I had some concerns at this visit, and she listened to everything I had say and addressed all of my worries. This might be an odd thing to say, but she does a very thorough breast exam- I never have to worry that something was missed, which is very comforting to me. She also does her "homework " ahead of time in reviewing patient records which facilitates a good conversation about my health. And we compare notes on her children and my grandchildren! It's always a pleasure to be seen by Maressa.
Marissa Sweeney is an expert at her practice. She addresses your concerns and gives a thorough exam. Pleased with the care I received at the Breast Care Clinic
An excellent and timely co ordination of 3 appoinrments.
Marrsss is so compassionate and listens to you, she explains things in a nice way. She answers your questions and cares about you as a person
She went above and beyond by following up with a specialty doctor outside the scope of our visiti and getting back to me with his comments.
Marissa is an excellent care provider- very compassionate & intelligent.
Maressa is a fantastic provider and is very empathetic. I appreciate her immensely.
Maressa always takes the time to listen to my concerns, address them and order any further testing that may be needed. She is knowledgeable and able to explain things in a helpful and compassionate way. I never feel rushed or dismissed in her care.
Marisa is a terrific listener and gives honest straightforward science based answers to questions. She is compassionate and just a wonderful medical professional. Outstanding.
